Pretty good
I gave it a 4/5 and 7/10.
The drums didn't really fit in so well. You should either drop them or maybe turn down the volume and use some other sounds.
Also, the part where it suddenly went louder could be at least turned down a littlebit.
You should also try adding some more instruments like voice, or violin or something like that which played at the same time. That would make it a bit more interesting.
Now that I've said what could be improved I'll say what I like about it.
I liked the instrument you used, it sounds pretty good and fits well with the song.
Even tho the drums could be better, it was still a nice touch to the song and gave it more life.
I also liked the voices or whatever it was, and the sound at the end which made looping it more interesting.
So overall a pretty good song. You should keep making melodies like this but make sure to do the improvements I told you and you'll get better. :)
